The origin and cosmogonic implications of seed magnetic fields.
Abstract
An evaluation is made of the possibility that cosmic magnetic fields derive their current strength from the process of dynamo amplification; the seed field required by this process is held to be a consequence of battery mechanisms in either protogalaxies or the first stars. Magnetic effects that influence star formation in the current epoch may not have been at work in the first stellar generation, so that the initial mass function and the star formation efficiency may for this single reason have been very different during the earlier eras of galactic history.
